(54) DESIGNING A MECHANICAL PART


(57) The invention notably relates to a computer-implemented method for designing, with a CAD system, a 3D modeled object representing a mechanical part. The method comprises providing a B-rep representing the mechanical part. The B-rep has faces, edges and vertices. The method comprises providing a sharp edge. The method further comprises, automatically by the CAD system, identifying a set of edges. The set of edges comprises the provided sharp edge. Each first edge of the set of edges is directed similarly to at least one second edge of the set of edges, the first edge and the second edge sharing a face. The method further comprises, automatically by the CAD system, selecting sharp edges within the set of edges. Such a method constitutes an improved method for designing a mechanical part.
